Democratic presidential candidate John Kerry says September 11, 2001 was the worst day in U.S. history - but that it brought out the best in the American people.

In his Saturday radio address, Senator Kerry gave examples of Americans pulling together after the terrorist attacks, including one in which Jews, Christians, and Muslims prayed together at a Pennsylvania mosque.

He said Americans will one day tell their children that the country came together in tragedy and chose confidence over fear.

Mr. Kerry said the country is united in its prayers for the victims and their families. He said America is also determined to, as he put it, "find and get the terrorists before they get us."
